His stories are distinguished by a strong connotation sadomasochistic themes but especially for the character trait of the graph. The design of Kovacq, although extremely realistic appears in some sections even slightly caricatured. The characters represented then, while maintaining a clear and explicit figurative reference, appear characterized by highly developed sexual organs, almost allegorical. Kovacq also not ashamed to be “bad”, who, with his features disharmonious, helps to accentuate the sadomasochistic image that is represented. Generally his stories are based on a female protagonist who, against his will, is to suffer (and subsequently to partecitare) to situations that reach the limit of perversion. Perhaps the author shows us an underwater world, that although hesitates, or has existed, is ignored by most.
